What's the difference between Licensed Data and Open data? Licensed Data is, as the name implies, data compiled from a number of our data providers. This data is updated quarterly and verified by our vendors, ensuring accuracy and reliability. Open data is compiled data from a global community within the Open Source Initiative. During their punfully-titled Mappy Hours, users gather to scope out streets, places of interest (POIs), and landmarks.
How do I know if I'm using Licensed or Open data? Quite simply, if your resource url has www.mapquestapi, you are using Licensed data. If it has open.mapquestapi, you're using Open data.
Can I use Extended Rights Geocoding (ERG) if I'm using Open data? Currently, ERG is only available to licensed data customers. For more information about ERG, click here.
